Walmart, Target, 7-Eleven, Sunoco and others are about to announce a Merchant Customer Exchange (MCX) standard for mobile payments in their establishments. The project is still being fleshed out, a CEO is about to be hired and so on, but the merchants say they know much more about the buyers' purchasing habits and history than, say, Google or the carriers.
Google does with its Wallet initiative, and the carriers, who are behind the ISIS system of mobile payments. Recently all those entered into a joint Mobile Payments Committee, designed to spearhead the adoption rate and iron out the differences between the numerous competing programs and standards, to which we recently had to add Starbucks with its Square cooperation.Speaking of which, they have a head start, at least
This doesn't bode well for the new retailers system, unless they are willing to participate in joint efforts for interoperability, about which Walmart's corporate vice president and assistant treasurer Mike Cook said the following: "We're open to all partners, but it has to be beneficial to member merchants in a way that improves the system and doesn't layer on additional costs".
